Abstract (en)
[origin: WO2010034684A2] A polyolef?n composition comprising, in percentage by weight based on the weight sum of the components (al), (a2) and (b): al) 16-78 % of a propylene homopolymer or copolymer containing at most 15% of ethylene and/or C4-C10 a-olefm(s), having an isotactic index over 80%; and a2) 6-44% of a copolymer of ethylene with one or more C4-C10 a-olefm(s) containing from 10 to 40%, preferably from 15 to 35%,of said C4-C10 a-olefm(s); b) 3-70% of a butene-1 (co)polymer having: - a content of butene-1 derived units of 80% wt or more, - flexural modulus (MEF) of 60 MPa or less. The polyolef?n composition exhibits good impact resistance, excellent whitening resistance and relatively low stiffness combined with good optical properties suitable for injection and blow molding, thermoforming and film application.
